Egress Window Size Requirements in Toronto

If you have a basement or any sleeping area below the main floor in your home in Toronto, understanding the size requirements for egress windows is important. These windows are not just for letting in light or fresh air; they also serve as essential emergency exits. The rules on window sizes help make sure that people can get out safely in case of a fire or other emergencies.

The Ontario Building Code clearly defines the size an egress window must have for it to be legal and functional. The primary goal is to make sure the window is big enough for someone to climb through easily. For a basement window, the window well around it also needs to meet specific size standards, so escape is not hindered.

Basic Window Size and Opening Dimensions

An egress window has two critical measurements: the opening size and the total window size. The Ontario Building Code states that the clear opening of the window, meaning the part you can actually crawl through, should be at least 0.35 square meters (about 3.77 square feet). That means the window opening must be at least 380 millimeters (15 inches) tall and 760 millimeters (30 inches) wide in all cases.

This size ensures that a person can physically fit through the opening. The height and width must allow a comfortable and safe way in and out. The window sill height, or how high the bottom of the window is from the finished floor, is also important. It can’t be higher than 1.5 meters (about 5 feet) to make sure the window is reachable without a ladder.

Remember, these measurements apply to windows used for bedrooms, living spaces, or any place where someone might need emergency access or exit. So, if you are planning to renovate or finish your basement, it’s wise to check the window size to stay within building codes.

Window Well Requirements

If your egress window opens into a window well, there are standards for the well size as well. The well must be large enough to allow easy escape and must not block the window opening. Its minimum size is 0.55 square meters (about 5.9 square feet), with a minimum horizontal projection and width of 760 millimeters (30 inches) each.

The depth and shape of the window well are important for safety. Toronto’s building inspectors look for enough space to step into. If the window well is too small or too narrow, it can become a barrier during an emergency. Therefore, having a properly-sized and installed window well complements the egress window’s function.

Why Following These Rules Matters

Beyond legal reasons, these size requirements exist because they protect you and your family. When they are met, an egress window works as a reliable emergency exit. It gives a second way out if doors are blocked and provides access for firefighters or rescue teams.

Correctly sized egress windows also improve natural light and ventilation in basements, making rooms more comfortable and healthy to live in. They turn what might otherwise be a dark, cramped space into a welcoming area while meeting safety standards.

If you are unsure about whether your current windows meet Ontario’s rules or if you want to install new egress windows, you can ask for professional advice.

Helpful Tips for Choosing Egress Windows

When looking for egress windows, there are things to keep in mind. The style of the window is important since some types open wider than others. Casement or awning windows usually provide larger openings than sliding or double-hung windows. This factor affects both safety and ventilation.

Another consideration is how easy the window is to open from the inside. Building codes generally require that the window can be opened without tools or special knowledge, and any bars or screens can be removed without keys or force.

Energy efficiency is also a factor in Toronto’s climate. Windows that help keep your home warm in winter and cool in summer can reduce heating and cooling costs. Look for products that have good insulation properties and airtight frames.

Since egress windows may require professional installation, working with a trusted company is ideal.
